Great work, thanks Simon.
I presume that there is no noticeable difference in brightness between
04 and 07 then?

Thanks Simon,
Looks like the KBCL variable is indeed the right one. Strange that it
changed from 01 to 04 rather than 01 to 05 though... If you have time
for a few more tests, I would love to know what values it takes when the
UEFI variable is modified from 00 through 07.
Currently we have:

Simon,
Sorry about that - there was a syntax problem in regions.c
I've just updated it so it should work properly now, if you are happy to
test it again.
The keyboard shortcut is currently set up to connect to the samsung
laptop kernel driver, but since the module is disabled on UEFI, the

Simon,
It looks like your UEFI variable has a different name:
KBDBacklitLvl-8be4df61-93ca-11d2-aa0d-00e098032b8c
Please do xxd on this and see if it looks similar to my
SecKeyboardBacklightLevel variable.

For those without KeyboardBacklight UEFI variables, can you attach a

If you are using UEFI, do not remove the blacklist on samsung-laptop!
You are probably safe from the bricking bug with a recent kernel, but
there are other UEFI problems with samsung-laptop that have never been
resolved, like machine check exceptions.
I did find a way of setting the keyboard back
For me this also leaves just the keyboard backlight, which doesn't work.
I believe that's a UEFI bug though, since Samsung's special hardware
features are disabled in UEFI mode.
If the backlight is working for you, this probably means you're not
using UEFI - although if you have your backlight wo
Thank you so much jaunmanuel!
I can confirm this is working on my NP900X3F.
Also, an easy way to check the command/data codes is:
$ dmesg | grep EC:
[0.119227] ACPI: EC: Look up EC in DSDT
[0.586520] ACPI: EC: GPE = 0x17, I/O: command/status = 0x66, data = 0x62
So no changes are needed
